Scope

Scope: This document applies to the large-scale seedling breeding of green shrimp; Main technical content: 4.1 Environmental conditions and supporting equipment - The breeding pond should be located near a water source with sufficient water volume, and the breeding environment should comply with the requirements of NY/T 5361. - The water quality of the water source should meet the standards of GB 11607. - The pond should be rectangular, with a length in the east-west direction. The pond embankment should be strong and have good leakproof performance. The soil should be loam or clay, with a relatively flat bottom and sediment no deeper than 15cm; the slope of the pond bank should be 1:2 to 1:3, with an area of 1,500 to 3,500 square meters, and a pond depth of 1.2 to 1.5 meters. It should also have complete water intake and drainage systems. The water intake should be filtered with a sieve bag made of a mesh size of more than 80mm. - The pond should be equipped with mechanical equipment such as pumps and aerators, with an aeration equipment of more than 0.2kW per 667 square meters of water surface. - Before stocking the parent shrimp, the pond should be sun-dried until the bottom is completely white, dry, and cracked. This usually requires more than 10 days of sun exposure. If it rains during this period, the sun-drying time should be extended appropriately. - 7 days before stocking the parent shrimp, 60cm of filtered water should be added to the pond. After stocking the shrimp, the water level should gradually increase to 0.8 to 1m until the shrimp larvae are cultivated. - 5 to 10 days before the shrimp larvae are cultivated, after adding 50 to 80cm of water to the pond, fertilizer-enriched water should be selected in accordance with relevant national regulations. - 15 artificial shrimp nests, each 60cm high and with a bottom diameter of 80cm, should be placed in the pond every 667 square meters. - Selection and stocking
